2. The gear system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring gear in 180° off-set relation with regards to the first planet locking equipment, about the entire 360° circumference of the ring gear, whereby said first and second planet gears rotate with said ring gear and also rotate about their personal respective installation axes while engaging said fixed and output spur gear the teeth, and whereby in the lack of rotation of the band gear a rotational power put on said output spur gear will drive said fixed and output spur gear the teeth to lock said first and second planet gears in place.
With reference to the application of the inventive gear system discussed herein, the system provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction via an input engine shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention could be effectively built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular program in neuro-scientific overhead lifting machinery, although the invention isn’t so limited. For example, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum must be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive equipment systems may also be applied to move scenery, create results, and manipulate overhead light and machinery during theatrical performances.
In the case of machinery that uses chain or screw jack components, a non-back driving, self-locking gearbox would offer benefits superior to existing configurations made up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type gear train further allow for a concise assembly. The system’s hollow through the center output spur shaft can complete wiring through to a rotating connection, along with the simple insertion of downstream apparatus shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronic devices up to speed, for example.
The inventive gear system moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the schedule lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a principal motor input and self-lubricating gear package. The primary motor input is definitely adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, ring plate and seal configuration, planet locking equipment, fixed spur equipment, and output spur equipment. The input ring gear is installed around the driveshaft and situated in meshing engagement with the primary motor input. The band plate and seal configuration are mounted to the ring gear and seal the components within the ring gear so as to allow the inner self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the planet gear rotates with the band gear and also rotates about its mounting axis. The result spur gear is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring equipment, and additional includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X quantity of gear tooth in meshing engagement with the planet gear. The fixed spur gear is fixedly installed around the result shaft and positioned next to the result spur gear. The fixed spur gear has N number of gear teeth in meshing engagement with the earth gear the teeth. The fixed and output spur gears have considerably similar diameters to permit the fixed and output spur gear teeth to considerably align while engaging with the earth equipment. The fixed and output spur gear the teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the primary electric motor input causes rotation of the band gear which in turn causes rotation of the planet gear which in turn causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the ring gear, any rotational push put on the output spur gear (e.g., via the output shaft) will pressure the considerably aligned fixed and result gear tooth to lock the planet locking gear in place.
Various other aspects of the machine are provided herein. For example, in an embodiment of the machine having two planet locking gears, the second planet locking gear could be rotatably mounted within the band gear in a 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° circumference of the ring gear. The initial and second world gears rotate with the ring gear and in addition rotate about their very own respective mounting axes while engaging the fixed and output spur gear the teeth. In the absence of rotation of the band gear, any rotational power applied to the output spur equipment will force the fixed and output spur gear the teeth to lock the first and second planet gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may or else add a sprocket in meshing engagement with a timing chain. The primary motor input may otherwise add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration could be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the output shaft to facilitate rotation of the result spur gear. The pressure angle configuration may be from about 45 degrees to about 25 degrees. The pressure angle configuration may more preferably be from about 40 degrees to 30 degrees. The pressure angle configuration may most preferably become about 35 degrees. The parts of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Additional objects, advantages and novel top features of the present invention will be established partly in the description which follows, and can in part become apparent to those in the practice of the invention, when considered with the attached figures.

Operation and Maintenance
Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a small tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear models are generally uneconomical when high performances and long operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is not possible. This is actually the case with ATLANTA wheel pieces and gear products when the lead position is usually <5°. A worm gear unit is considered self-locking from the working condition if the apparatus unit involves a standstill whilst becoming backdriven. This is only feasible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! As a result a self-locking tooth system cannot replace a brake or reverse-stroke locking mechanism. To avoid overstressing of the worm equipment drive due to the very high kinetic energy involved, you should furthermore enable a certain running-down time after stopping the input.
